Hi-Lo Drop Frame ISO Tank Chassis

Our 44ft Hi-Lo Drop Frame Tank Chassis is not just an add-on bolster that you install on a standard tank chassis.  Rather, it is a tank chassis specifically designed to transport two empty 20ft ISO tank containers in addition to a loaded one.  With a robust frame tipping the scale at 9,700 lbs, 25k axles, and air suspension, you can rest assure that this tank chassis will outlive its half siblings.  Not to mention that its 102" width provides for greater stability.

Chassis is designed and built acccording to Association of American Railroads (AAR), Federal Motor Vehicle Safety Standards (FMVSS), International Standards Organization (ISO), American National Standards Institute (ANSI), Department of Transportation (DOT), American Bureau of Shipping (ABS), Society of Automotive Engineers (SAE), and Truck Trailer Manufacturers Association (TTMA) standards.

Low profile tires on 10-hole hub piloted disc wheels, air suspension, and flip-up type type twistlocks are all standard.  The chassis is lift ready with lift kit optional.  Other options include full width decking, and aluminum wheels and hubs.

Chassis can be stacked up to 3 high for power only transport.
